AI Technical Summary
Existing technologies are difficult to effectively purify trifluoroiodide methane (CF3I), especially to remove impurities, and it is difficult to predict the formation of azeotropes or azeotropic-like substances.
A method for forming a heterogeneous azeotrope or azeotropic composition by trifluoroiodomethane (CF3I) and water has been discovered and provided. By adjusting the relative amounts of the two components and forming the azeotrope or azeotropic composition under a specific pressure, impurities can be separated using techniques such as phase separation and distillation.
The formation of an azeotrope or azeotropic-like composition of trifluoroiodoformane (CF3I) and water under specific pressure was achieved, effectively separating and purifying trifluoroiodoformane (CF3I) and reducing impurity content.
